UNITED, STATES PATENT OFFICE. I

' 1 Clai ml (o 30-11) This invention relates to improvements in pruningshears, the general object of the invention being to provide adetachable blade. and also to provide means for preventing the pivot nutfrom working loose and to remove side strain on the bolts. Anotherobject of the invention is to so position the pivot as to provide a drawout between the cutting members. I

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claim.

In describing the invention in detail, reference will be had to theaccompanying drawings wherc in like characters denote like orcorresponding parts throughout the several views, and in which:-

Figure l is a side view of the complete device in open position.

Fig. 2 is a section on line 2--2 of Fig. 1.

Fig. 3 is a view of the blade.

Fig. 4 is a view of the blade carrying member looking towards the innerface thereof. v

Fig. 5 is a view of the opposite member looking towards the outer side.

Fig. 6 is a, view looking towards the opposite side of the member shownin Fig. 5.

Fig. '7 is a view of the plate.

In these drawings, the letter A indicates the hook carrying member andthe letter B the blade operating member, each member consisting of ahandle part and a head part, the head part of the member A being shownat l and the head part of the opposite member being shown at 2. The headpart I is formed with the substantially hookshaped projection 3 whichcooperates with the knife in the cutting operation. The two head partsare. pivotally connected by the bolt =1 which passes thru an opening 5in the head part i and through an opening 6 in the head part 2. Theknife is shown at i. and is provided with a head part 8 which has a hole9 therein'through which .the bolt 4 passes and with a diagonallyarranged elongated opening H! for receiving the similarly shapedprojection l l on the inner face of the'part 2. This knife has its headpart located between the head parts I and 2 and a plate l2 of the shapeshown in Fig. 7 is fastened to the member B at the junction of the shankwith the head part, by the two screws l3 and the bolt 4 also passesthrough a threaded hole H! in the plate. As shown in Figure 2, the plateI2 overlaps the major portion of the head part I of the member A so thatthe bolt 4 has one end supported by the part 2 of the memberB and itsother end sup ported by the plate it which is attached to' a part 'ofthemember B. -Thus this plate provides strength for the cutting assembly ofthe shears and at the same time provides a direct bearing for the nutcarrying end of the bolt andalso provides a bearing surface for the hookcarrying member A. This plate also removes all side strain on the bolt.

Springs 05 on the handle parts tend to hold the device in open positionas shown in Fig. 1. The blade is of the shape shown in Fig. 3 and itscurved cutting edge will cooperate with the part 3 in the cuttingoperation.

The major portions of the head parts I and 2 A are reduced in thicknessso as to form the curved shoulder E6 on the member A and the irregularshaped shoulder i! on the member B, these shoulders being. so arrangedrelative to each other as to limit the opening and closing movement ofshouider ii, a part of which the shoulder 19 forms a continuation. Thehead part of the blade is of the same thickness as the height of theshoulder i 9 so that the raised part i8 is flush with the head part ofthe blade when the blade is in position. i

As will be seen, the blade or knife can be detached from the other partsto facilitate its being sharpened and the plate l2 acts as a lock forthe pivot bolt thereby avoiding the nut working loose, as the nut on thebolt does not come in contact with any working parts. The plate alsoremoves side strain on the bolt and said plate can be detached when theparts become wornand that part of the plate which contacts the thickenedpart of portion 2 filed so that when the plate is put back in place thewear will be eliminated. The plate also acts as a'protector againstpinching of the fingers as said plate will prevent, the fingers fromentering the space formed by the members A and B when the members are inopen position.

The blade has three bearings so that there is no chance of the bladeworking loose tad tion abuts this shoulder i9 and portions of the as itwill move with the part B through connection with said part throughmeans of the .projection H and the slot Ill. The bolt does notturn sothat there is no wear on the bolt or the hole in the blade. The member Ais the only part that turns on the bolt.

The bolt being offset about three-quarters of an inch from center ofhandles and about onehalf inch in ahead of center gives more leverage onhandle and also gives about three-quarters that such changes fall withinthe scope of the appended claim.

Having thus described my invention, what I claim as new is:

Pruning shears of the class described compris-' ing a pair of members,each having 'a head part and a handle part, the head part of one memberbelngof considerble width and the head part of the second memberextending upwardly and forwardly, each head part being recessed on itsinner face and having a hole in its upper part, a blade having a headpart fitting in the space formed by the recesses and said head part ofthe blade having a hole adjacent its upper edge and adjacent thejunction of said head part with the blade, the three holes registering,a bolt passing through the three holes, a non-circular projection on Ithe inner face of the head part of the second member and the head partof the blade having a non-circular opening for receiving the projection,said projection and hole being below and in rear of the holes in saidhead parts, a plate of substantially the same shape as the head part ofthe second member, screws fastening the lower end of the plate to theouter face of the lower end of the head part of the second member, saidplate extending over the outer face of the head part of the first memberand having a threaded hole in its upper end for receiving the threadedpart of the bolt, a nut threadedon the bolt and contacting the plate,and a hook extending from the head part of the first member.

ODEL FOWLER.
